Management of Prior Knee Fusion
Fusion of the knee is a singularly difficult operation to accomplish. The indications are usually chronic infection after multiple previous total knee procedures, complicated traumatic injury to the knee leaving no significant surfaces for a replacement procedure, or a tumorous condition. On occasion, there may be an unusual case that is considered for conversion to total knee arthroplasty after a successful fusion. This presents one of the most difficult of all reconstructive procedures for the knee. Infection must be ruled out, the condition of the extensor mechanism must be evaluated, and the status of the skin must be clarified. There are a few papers in the literature that support this approach and report reasonable results.
